68268285AC FUEL WATER SEPARATOR ASSEMBLY FOR 2013-2018 RAM 6.7L CUMMINS

iFJF part No.: FJ-67AA-ZH. Overview The iFJF 68268285AC Fuel Water Separator Assembly is a direct OEM-grade replacement for the chassis-mounted fuel filter housing on 2013-2018 Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins Turbo Diesel engine. This complete assembly includes the integrated primer pump, water-in-fuel (WIF) sensor connector, drain valve, and mounting bracket everything you need for a drop-in replacement. Water contamination is the #1 cause of premature injector failure in modern diesel engines. The high-pressure CP4.2 injection pump and piezo injectors in the 6.7L Cummins have extremely tight clearances even a few drops of water passing through can cause catastrophic damage ($4,000-$8,000 repair cost). This separator assembly ensures reliable water separation and fuel filtration at every fill-up. Key Features Complete Assembly Includes filter housing, primer pump, WIF sensor port, drain valve, and mounting bracket pre-assembled OEM-Grade Construction Manufactured to OE specifications with high-grade composite materials resistant to diesel fuel and biodiesel blends Integrated Primer Pump Makes fuel system priming after filter changes fast and tool-free no more cranking the starter WIF Sensor Port Direct plug-and-play with factory water-in-fuel sensor for dashboard water detection warning Easy Drain Valve Accessible drain port allows quick water purging during routine maintenance without removing the filter Protects $4,000+ Fuel System Effective water separation prevents catastrophic CP4.2 pump and injector failure Direct Cross-Reference Replaces Mopar 68268285AC, 68197866AA, 68197866AB, 68197866AC, 68268285AB Chassis-Mounted Design Factory-correct location under driver-side frame rail for easy access during oil changes Technical Specifications Specification Details Part Number 68268285AC (Replaces 68197866AA/AB/AC, 68268285AB) Vehicle Fitment 2013-2018 Ram 2500/3500/4500/5500 6.7L Cummins Filter Type Fuel Water Separator Assembly (Chassis-Mounted) Includes Filter Housing, Primer Pump, WIF Sensor Port, Drain Valve, Bracket Material High-Grade Composite / Aluminum Bracket Compatibility Year Make Model Engine 2013-2018 Ram 2500 / 3500 6.7L Cummins I6 Turbo Diesel 2013-2018 Ram 4500 / 5500 (Chassis Cab) 6.7L Cummins I6 Turbo Diesel Installation Guide Relieve Fuel Pressure Open the fuel filler cap to release tank pressure Locate Assembly Chassis-mounted housing on the driver-side frame rail, near the fuel tank Disconnect Quick-Connect Lines Use fuel line disconnect tool; have rags ready for fuel spillage Unplug WIF Sensor Disconnect the electrical connector from the water-in-fuel sensor Remove Mounting Bolts Typically 2-3 bolts securing the housing bracket to the frame Install New Assembly Bolt in the iFJF replacement, reconnect lines and WIF sensor Prime System Pump the integrated primer until firm resistance is felt Cycle Key & Start Cycle key to "Run" (not start) 3 times to prime, then start and inspect for leaks Why Replace Your Water Separator? Prevent $4,000-$8,000 Injector Failure: The CP4.2 high-pressure pump and Bosch piezo injectors are extremely sensitive to water. A cracked housing or leaking primer pump compromises water separation allowing water to reach the injection system. Replacement is far cheaper than injector/pump repair. Stop Diesel Leaks: Cracked filter housings and degraded seals create a fire hazard and fail DOT inspections. A complete assembly replaces all wear-prone components i
